Embodiment
Be described further in conjunction with the embodiment of accompanying drawing the utility model.
A kind of mechanism that is used for accurately adjusting the cylinder stroke; Comprise adjustment seat 3, adjustment nut 4, locking nut 5; The outer cylinder surface of adjustment nut 4 is carved with the axial graduation line 6 of five equilibrium, and adjustment seat 3, adjustment nut 4, locking nut 5 are contained on the twin shaft cylinder axis 2 successively.Cylinder 1 end face is close in the bottom surface of adjustment seat 3, and the diameter of bore of adjustment seat 3 equates with the external diameter of adjustment nut 4.Adjustment nut 4 diameter of bores have the protruding seat of a band interior threaded hole more than or equal to the external diameter of locking nut 5 in adjustment nut 4 endoporus, is connected with outside thread on the cylinder axis 2 through internal thread, and adjustment nut 4 is contained in adjusts an endoporus of 3.The outer cylinder surface of adjustment nut 4 is carved with the axial graduation line of five equilibrium, evenly divided line number=pitch/adjustment precision.The external diameter of locking nut 5 is less than or equal to the diameter of bore of adjusting nut 4; The end face that stretches into adjustment nut 4 endoporus has interior threaded hole; Be connected with the outside thread of cylinder axis 2; This end face is fitted on the protruding seat that has interior threaded hole of adjustment nut 2, has locking effect, and another larger diameter end outer surface of locking nut 5 has the ridge design of being convenient to regulate rotation.
The utility model at first will be adjusted seat 3 and be sleeved on the cylinder axis 2 when assembling, and cylinder 1 end face is close in the bottom surface of adjustment seat 3; Adjustment nut 4 is contained in the endoporus of adjustment seat 3; Be connected through outside thread on internal thread and the cylinder axis 2, by adjustment nut graduation line 6 rotation adjustment nuts 4, accurately positioning piston strokes; Rotational lock nut 5 is pressed on the protruding seat of interior threaded hole of adjustment nut 4 until the internal thread end face then, and adjustment nut 4 is locked.
When needs are adjusted piston stroke, unclamp locking nut 5, by adjustment nut graduation line 6 rotation adjustment nuts 4, revolution is crossed a graduation line; Piston stroke just changes the distance of " pitch/graduation line number ", and (for example, the adjustment nut is: M14X1.5; When the adjustment precision was 0.01, the graduation line number was 150, during graduation line of every rotation; Piston stroke will change the 1.5/150=0.01 millimeter, realize the accurate fine setting of piston stroke) tighten locking nut 5 then, accomplish the stroke adjustment.
